Product Introduction


LONN-4GX high temperature pressure transmitter adopts the high-accuracy and high-stability force sensitive chip with stainless steel isolation diaphragm to realize temperature and linear compensation, signal amplification, V/I switch, inverse polarity protection, and current limiting when pressure overloaded through laser resistor trimming and advanced thick-film technology. It outputs industry-standard 4-20mA or 0.5-4.5V signal. The process connection comes with a radiator to lower the temperature so as to have a good measurement result.


Product features

  • High accuracy and reliability with Germany-made chip;
  • The probe comes with a radiator and can measure the temperature range of -40 ℃ ~ 150 ℃;
  • Built-in anti-interference circuit and isolated from external environment;
  • Two-wire system standard 4-20mA signal output; customized RS485 signal signal output is available;
